Carb runs good for a few miles than runs not smooth bumping and idling low. Hitting the right hand bolt if you're facing the cab with a hammer fixes the problem temporally, Anyone know the problem and any permeant fixes or adjustments, rebuild kit?

You may want to contact Marshall, Mr. Trollhole......FWIW - I don't think a hammer and any carburetor go together very well. However, there are a few screws that adjust the idle, the (choke) fast idle and the idle mixture screw. Do a search and you will probably find what you are looking for.Carb runs good for a few miles than runs not smooth bumping and idling low.

Maybe you ust need a bigger hammer?
"....other unwanted stuff in the gas?"....you may want to check your fuel filter, make sure you have one first, and then if you do, make sure it is working.Thanks the harbor freight fj40.thc-01 hammer works perfectly... but really thanks guys drained the bowl and found shavings and other unwanted stuff in the gas.
When I got a trollhole, it ran great for a while and then ran poorly. I assumed that it couldn't be the carb because it was brand new. I looked at everything else and then opened up the carb-it was full of shavings. A few others have reported this problem and has he handled them professionally. What i would do is to get a paper towel and open up the bowl drain bolt. Let the bowl drain through the paper towel. If it's full of metal shavings, you might have this problem. If it's clean, then check everything else (vacuum, etc).
That Manufacturer was from only one batch. Big mistake on my part. Nothing in the past two years, maybe more, has had this issue. Went back with my original manufacturer.
My biggest issue I had in the beginning was the rivets would leak. Got that fixed a long time ago. Now a majority of the problem is with our stupid american ethonal gas. It's a crap shoot but from time to time. if someone runs e85 accidentally or just get a really strong tank of more than 10% ethanol. Which happens. It can melt the prescreen above the float needle. If this happens all kinds of weird things can happen. Best thing to do is remove the top half of carb gently trying not to damage the gasket. You want the gasket to come off with the top half. I use a long razor knife or putty knife. Then remove float. Then remove gasket. They usually come off in one piece. Then break the seal on the brass needle seat with a pair of vise grips then unscrew with a flat screwdriver. Remove the screen and reassemble.
